Abstract: Image noise will degrade image quality and subsequent image processing will be affected. To eliminate noise while keeping image edge details, a new algorithm was proposed. It took full consideration of wavelet coefficients correlation using the phase invariance, and estimated the skeleton information in reference to morphology, and performed de-noising based on the selected congenial and irregular regions. The experimental results demonstrate that the proposed algorithm can keep details of images as well as reduce image noises.
